AimTo reconstruct spatial and temporal patterns of European fire activity during the Holocene and to explore their potential drivers, by relating biomass burning to simulated biotic and abiotic parameters. LocationEurope. MethodsHolocene fire activity was investigated based on 156 sedimentary charcoal records from lakes and peat bogs across Europe. Charcoal data covering the last 9000 years were s
Objectives: First, to outline the theoretical and practical framework for geriatric rehabilitation in the Nordic countries and second, to survey the scientific medical publications for evidence-based geriatric rehabilitation. Methods: Brainstorming on geriatric rehabilitation in a working group of Nordic teachers in geriatric medicine. Papers on scientific programmes for geriatric rehabilitation f
This article is the second part of research on amylose-lipid complexes, where the first article dealt with monoglycerides. Here, a variety of fatty acids with chain lengths between 3 and 22 carbons and with varying degree of unsaturation were studied regarding their ability to form amylose-lipid complexes. In the present paper it is intended to investigate the formation of different fatty acid- am
Aim. To study nurses' compliance to national guidelines (Sweden) for peripheral venous catheters and to establish the complication frequency connected to time in situ and bore size. Background. Worldwide, there are no standard peripheral venous catheters guidelines, and the need for elective replacement has been challenged. Furthermore, the time interval and need for elective change of peripheral
BACKGROUND: There is conflicting evidence that traffic-related air pollution is a risk factor for allergic conditions. Few studies have investigated this in adults. In adults, a high proportion of asthma, rhinitis and eczema is triggered by non-allergic factors. We investigated traffic as a risk factor for allergic versus non-allergic asthma and rhinitis, and eczema, in adults. A questionnaire fro
This thesis is an exploratory, descriptive and comparative study of teachers’ focus and teaching methods in Spanish as a third language (L3) in Sweden. The curriculum of Modern Languages emphasizes communicative competence and the purpose of the study is to examine how this is applied in the teaching of the course Spanish 4 and how the students progress during the course. Five teachers at four Sen
Context: The age-related decline in dehydroepiandrosterone (DHEA) levels is thought to be of importance for general and vascular aging. However, data on the association between DHEA and mortality are conflicting. Objectives: We tested the hypothesis that low serum DHEA and DHEA sulfate (DHEA-S) levels predict all-cause and cardiovascular disease (CVD) death in elderly men. Design, Setting, and Par
Popular Abstract in Swedish Nanoteknik och nanotrådar omnämns ofta media idag, men vad är egentligen en nanotråd, och vad kan den användas till? Dagens datorer, lysdioder och solceller är till stor del beroende av halvledare. En halvledare är ett kristallint material där man enkelt kan ändra ledningsförmågan. Man kan dels bestämma ledningsförmågan när materialet tillverkas genom att tillföra ytterThis thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. The first part of the thesis describes the development of Hall effect measurements, an entirely new characterization tool for nanowires. It is shown that Hall effect me
In order to reduce parasite-induced mortality, hosts may be involved in mutualistic interactions in which the partner contributes to resistance against the parasite. The pea aphid, Acyrthosiphon pisum Harris (Hemiptera: Aphididae), harbours secondary bacterial endosymbionts, some of which have been reported to confer resistance against aphid parasitoids. Although this resistance often results in d
Purpose: To develop concise, patient-focussed, up to date, evidence-based, expert consensus recommendations for the management of hip and knee osteoarthritis (OA), which are adaptable and designed to assist physicians and allied health care professionals in general and specialist practise throughout the world. Methods: Sixteen experts from four medical disciplines (primary care, rheumatology, orth
Background and purpose — Patients having a total knee arthroplasty (TKA) after a previous high tibial osteotomy (HTO) constitute a minor group among those undergoing primary TKA for knee osteoarthritis (OA). There have been few reports on whether such patients differ pre- and postoperatively from those who undergo TKA as the first measure. We evaluated patient characteristics, knee-related pain, f
The possibility of using radio over fiber (RoF) analog transmissions to characterize the wireless propagation channel of distributed antenna systems is investigated. In particular, the coherence time of kilometer-long, fiber-based networks is analyzed. Joint measurements of the phase noise of parallel links to the same site (intra-site) and to different sites (inter-site) in such a network are pre
Background. Anaemia in haemodialysis patients can be effectively treated with erythropoietin. We investigated whether subcutaneous (SC) epoetin β administered once weekly was as effective as the same weekly dosage given in two to three divided doses. Methods. One hundred and fifty-eight patients (delivered Kt/V >1.0, where K=dialyser-renal urea clearance, t=dialysis time and V=filtration volume, o
Background: When cannulation is challenging during endoscopic retrograde cholangiopancreatography (ERCP), and the standard guidewire technique with sphincterotomy is unsuccessful, alternative cannulation techniques can be used to access the biliary tree. The purpose of this study was to compare the incidence of adverse events and cannulation success rates between transpancreatic sphincterotomy (TP
We propose symmetrical cationic trimethine cyanine dyes with β-substituents in the polymethine chain based on modified benzothiazole and benzoxazole heterocycles as probes for the detection and visualization of live and fixed cells by fluorescence microscopy. The spectral-luminescent properties of trimethine cyanines have been characterized for free dyes and in the presence of nucleic acids (NA) a
BACKGROUNDRecanalization sometimes fails during endovascular thrombectomy due to target vessel access failure. Two‐dimensional/3‐dimensional fusion imaging in the Siemens ARTIS Icono biplane platform may facilitate access by fusing the preoperative computed tomography angiography with procedural imaging. This observational study aimed to evaluate vascular access, success rates, and procedure times

Svensk lagstiftning om offentlig upphandling bygger på EU-direktiv. Grundtanken bakom upphandlingsdirektiven är att värna om de friheter som följer av den inre marknadens reglering och att bidra till en effektiv konkurrens där upphandlande myndigheter från olika medlemsländer ska kunna tävla om offentliga kontrakt på lika villkor. En upphandlande myndighet som på förhand har svårt att bestämma voSwedish legislation on public procurement is based on EU-directives. The basic idea behind the public procurement directives is to protect the freedoms derived from the regulation of the internal market and to contribute to effective competition in which contracting authorities from different Member States should be able to compete for public contracts on equal terms. A contracting authority that
Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in
The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. The initial design was known to function with current materials and dimensions. The first step of the thesis was
